Finished true end.
Story was kinda of an interesting mess of a wacky creative idea that wasn't really thought through very well. It's actually pretty similar to the movie Triangle in a lot of ways besides the fact that they're both on an ocean liner. It had good characters, some cute parts, some funny parts. But, like most Japanese plot-twisty stuff, they go way way overboard and there are some serious plot holes. Was worth sticking through, mainly because a lot of the game is the presentation of the story which can be both for better (the impact of scenes) or worse (sloooow text and hour long cutscenes). I think my main complaint besides the plot holes is that the puzzles are a joke. Sure I've been playing adventure games forever, but I'm not particularly great at them and usually need to faq parts here and there; but everything in 999 was super linear and straight forward. It's like the puzzle part is made for 5 year olds, which is just a bit disappointing since the puzzle rooms are fun and the only thing to break up the hours and hours of slow text.
Was maaaaaybe better than PW2, but still one of the weaker VNs I've played. It's just too freaking long (because of the text speed) and the story is obscure for most of it with nothing happening and then just kind of wacko/lolz by the ending.
Not going to bother with the sub ending. Sure it has two juicy sounding puzzle rooms (CONFINEMENT, TORTURE CHAMBER), but I don't see how there'd be much worthwhile plot to get out of it and pretty burnt out on the game by this point. Will read up on the SPOILER FAQS/Q&As to get a little more out of the plot.
